My DVD only read CDs

I have a Ricoh CD/CDr/DVD. A friend of mine have burned a DVD-r of 4.7 Gb and it works with his computer.
But in my house it don’t appears anything. When I go to My Computer and I try to open the DVD, it says that it is a blank CD and has 0 bytes.
Why?:confused:

Is your reader capable of reading DVD-r’s? Does this only happen with DVD-r or with all DVDs? If you give an answer to these questions, some other people will be able to help you.
